The components shown in FIG1A are illustrative. The information processing system may include all or some of the components in FIG1A, or may include other components outside of FIG1A.

[0184] The embodiments disclosed herein can be applied to Long Term Evolution (LTE), LTE-Advanced (LTE-A), LTE-Beyond (LTE-B), SUPER 3G, IMT-Advanced, 4th generation mobile communication system (4G), 5th generation mobile communication system (5G), 6th generation mobile communication system (6G), 5G New Radio (NR), Future Radio Access (FRA), New-Radio Access Technology (RAT), New Radio (NR), New Radio access (NX), Future generation radio access (FX), Global System for Mobile communications (GSM), CDMA2000, Ultra Mobile Broadband (UMB), IEEE 802.11 (Wi-Fi), IEEE 802.16 (WiMAX), and IEEE 802.20, Ultra-Wideband (UWB), Bluetooth (a registered trademark), Public Land Mobile Network (PLMN) networks, Device-to-Device (D2D) systems, Machine-to-Machine (M2M) systems, Internet of Things (IoT) systems, Vehicle-to-Everything (V2X) systems, systems utilizing other communication methods, and next-generation systems built upon them, etc. Furthermore, multiple systems can be combined (e.g., LTE or LTE-A combined with 5G, 5G combined with 5G, 5G combined with 6G, etc.) for application.

[0185] In some embodiments, different types of satellites exist at different orbital altitudes, such as geostationary orbit (GEO) satellites at approximately 36,000 km above Earth, medium Earth orbit (MEO) satellites at 5,000 to 20,000 km above Earth, and low Earth orbit (LEO) satellites at 500 to 1,500 km above Earth. These differences in satellite altitude result in different performance characteristics. For example, GEO satellites can provide large-area continuous coverage with fewer satellite switches, while LEO satellites can support services requiring low latency.

[0186] In some embodiments, a multi-orbit satellite access system is a network of services provided by satellites operating in different orbits. Each orbital altitude in the satellite network offers unique benefits to the entire ecosystem. With the surge in global connectivity demand, multi-orbit satellite solutions offer tremendous opportunities to supplement global coverage with terrestrial networks and allow mobile network operators to deploy hybrid solutions (using GEO and non-geosynchronous orbit NGSO satellites) for ubiquitous coverage and higher capacity.

[0187] In some embodiments, the greatest challenge for satellite networks lies in the fact that satellites operate in a power-limited environment in space, relying on solar panels to generate and store electrical energy to power their equipment. In particular, NGSO (LEO & MEO) satellites limit the size and capacity of their solar panels and batteries, making them more compact compared to GEO satellites. Another aspect is that NGSO satellites are subject to atmospheric drag, requiring frequent orbital adjustments, which further consumes energy.

[0188] In some embodiments, NGSO satellites, due to their proximity to Earth, can provide higher capacity and lower latency compared to GEO satellites, playing a crucial role in providing connectivity with ships, aircraft, offshore platforms, and remote islands.

[0189] In some embodiments, a 5G system with multi-orbit satellite access should leverage the advantages of each orbit to ensure optimal energy and resource efficiency of the satellite access network. For example, to achieve resource efficiency, when the UE is active, it can connect to a GEO satellite and maintain the connection there. If the UE needs to transmit data, it can switch to LEO satellite access.

[0190] In some embodiments, many UEs are power-constrained and need to conserve power to extend battery life. In some cases, UEs receive (or must transmit) packets very infrequently. In these cases, it is wasteful for the UE to continuously maintain and establish synchronization with NGSO satellites that need to be tracked in the sky. GEO satellites can be very useful for these UEs. GEO can provide access to the UE. If the UE needs data transmission, it can switch to NGSO access.

[0191] In some embodiments, in order to save energy for the UE and satellite network (especially LEO and MEO), it is proposed that the UE use basic network services provided by GEO (such as network access or small data transmission services provided by GEO for the UE), and when the services provided by GEO network do not meet the service transmission requirements, the NGSO (LEO or MEO) provides network services for the UE.

[0192] In some embodiments, please refer to Figure 1B, which illustrates a network architecture in which a UE can access the same Public Land Mobile Network (PLMN) through satellite access networks of multiple orbit types. That is, the UE can access the PLMN through LEO, or through GEO or MEO. The UE can select the same or different Access and Mobility Management Function (AMF) when accessing through LEO and the Access Management Function when accessing through GEO, but they can select the same Session Management Function (SMF) and User Plane Function (UPF).

[0193] It should be noted that the embodiments disclosed herein only describe the network configuration based on network functions, and the network architecture can be applied to 5G or 6G networks. As networks evolve, the network architecture can also be applied to other evolved networks, and this is not limited thereto.

[0234] In some embodiments, the first network device processes the information to obtain the second information, in which case step S2102 can be omitted.

[0235] In some embodiments, the first network device autonomously implements the function indicated by the second information, or the above function is a default or default value, in which case step S2102 can be omitted.

[0236] In some embodiments, the terminal determines that the switching conditions are met and sends second information to the first network device.

[0237] In some embodiments, the second information is used to request a switch of execution path.

[0238] In some embodiments, the path switching will only be performed after the terminal receives the corresponding response information after sending the second information to the first network device.

[0351] In some embodiments, the switching of the data transmission path further includes the first control network element sending data transmission path information to the terminal and / or the first user plane network element, wherein the data transmission path information is used to indicate the use of the second network to transmit data.

[0352] In some embodiments, the method further includes establishing or activating a connection between the UE and the second network.

[0353] In some embodiments, the first control network element is an AMF, SMF, or PCF; the first user plane network element includes a PSA-UPF or an I-UPF.

[0354] In some embodiments, the first network is a GEO access network, and the second network is a LEO access network or a MEO access network.

[0355] Example 1

[0356] As shown in Figure 4A, this embodiment describes a UE accessing the network via GEO and detecting that the Packet Data Unit (PDU) session established using the GEO access network does not meet the transmission requirements of the service data stream. The UE is then instructed to switch to another access method to ensure the data stream can be transmitted. In Figure 4A, GEO-RAN is the access network function integrated on the GEO satellite, and LEO-RAN is the access network function integrated on the LEO satellite; GEO-RAN and LEO-RAN are different access networks. AMF is the network function responsible for user access management, SMF is the network function responsible for user session connection management, PCF is the policy management function, I-UPF(G) is the intermediate user plane function selected by the UE using GEO-RAN access, I-UPF(L) is the intermediate user plane function selected by the UE using LEO-RAN access, UPF(PSA) is the anchored user plane function, and UDM is the unified data management function. The network elements mentioned only represent the network functions performed and can be applied to 5G or 6G networks. In Figure 4A, the first control network element corresponds to AMF, SMF, or PCF; the second network element corresponds to UPF (PSA); the first access network corresponds to GEO-RAN, and the second access network corresponds to LEO-RAN.

[0357] As shown in Figure 4A, an information processing method is provided, including the following steps:

[0358] Step S4101: Complete network registration based on GEO.

[0359] In some embodiments, the UE selects the GEO access network and completes registration through GEO access.

[0360] Step S4102: Establish a PDU session based on GEO.

[0361] In some embodiments, the UE establishes a first Packet Data Unit (PDU) session via GEO access.

[0362] In some embodiments, during the session establishment process, the AMF provides a first rule to the UE and the UPF (PSA).

[0363] In some embodiments, the first rule includes at least one of the following:

[0364] A new service data stream was detected, and an instruction was given to use LEO access for transmission of the service data stream;

[0365] Network switching threshold: When the cumulative transmission rate on GEO access reaches the threshold, LEO access will be used for transmission of new data streams.

[0366] QoS parameters, including bandwidth and / or latency and / or packet loss rate, such as configuring latency and corresponding GEO or LEO access. When the latency requirement of the service data stream matches the first rule, the corresponding access is used for transmission.

[0367] Step S4103: Save the first rule.

[0368] In some embodiments, the corresponding first rules are stored on the UE and UPF (PSA), respectively.

[0369] Step S4104: Send service data.

[0370] In some embodiments, the UE decides to initiate a new service and sends the uplink data stream corresponding to the service.

[0371] Step S4105: Complete LEO registration.

[0372] In some embodiments, when the first rule matches the data flow of the service that requires LEO access, if the UE has not yet registered for LEO access, the registration process is initiated.

[0373] Step S4106: Establish a PDU session based on LEO.

[0374] In some embodiments, the UE uses the LEO access to establish a second PDU session.

[0375] Step S4107: Transmit service data via LEO.

[0376] In some embodiments, according to the first rule, the service data stream uses a second PDU session, i.e., it is transmitted using LEO access.

[0377] In some embodiments, when the data stream transmission ends and the second PDU session has no data transmission within a specified time, the second PDU session can be deactivated, or a process of registering from LEO access can be initiated to reuse GEO access.

[0378] As shown in Figure 4B, an information processing method is provided, including the following steps:

[0379] Step S4201: Complete network registration based on GEO.

[0380] In some embodiments, the UE selects the GEO access network and completes registration through GEO access.

[0381] Step S4202: Establish a PDU session based on GEO.

[0382] In some embodiments, the UE establishes a first Packet Data Unit (PDU) session via GEO access.

[0383] In some embodiments, during the session establishment process, the SMF issues a first rule to the UPF (PSA).

[0384] In some embodiments, the first rule includes at least one of the following:

[0385] A new business data flow has been detected, indicating that the detection result should be reported when a business data flow is detected.

[0386] Network handover thresholds, such as configuring a data transmission threshold or session connection threshold on the UPF (PSA) or an access user count threshold on the AMF or SMF; the detection result is required to be reported when the threshold is met;

[0387] QoS parameter mismatch, where the QoS parameters include bandwidth and / or latency and / or packet loss rate, means that the QoS parameters do not meet the QoS requirements of the service data, and the detection result is reported.

[0388] Step S4203: Save the first rule.

[0389] In some embodiments, the corresponding first rule is stored on the UPF (PSA).

[0390] Step S4204: Receive data stream.

[0391] In some embodiments, the UPF(PSA) receives downlink service data streams.

[0392] Step S4205: Detect downlink data.

[0393] In some embodiments, the service data stream is detected by the first rule, that is, the service data stream is a new service data stream, or the service data stream has reached the switching threshold, or the QoS of the service data stream does not match the QoS in the first rule.

[0394] Step S4206: Send the first instruction.

[0395] In some embodiments, the UPF (PSA) sends a first indication to the PCF via the SMF, the first indication being used to indicate the detection event described in step S4205.

[0396] Step S4207: Determine the data matching rules.

[0397] In some embodiments, the PCF formulates data matching rules for the business data stream and sends them to the UPF (PSA) through the SMF.

[0398] Step S4208: Save the data matching rules.

[0399] In some embodiments, the UPF (PSA) stores the data matching rules.

[0400] Step S4209: Activate the PDU session based on LEO.

[0401] In some embodiments, the UPF (PSA) initiates the activation of a second PDU session according to the data matching rules. The second PDU session is established via LEO access but is in an inactive state when no data is being transmitted.

[0402] Step S4210: Send the data stream.

[0403] In some embodiments, according to the data matching rules, the UPF (PSA) sends the service data stream to the UE through a second PDU session.

[0404] In some embodiments, when the data stream transmission ends and the second PDU session has no data transmission within a specified time, the second PDU session can be deactivated, or a process of registering from LEO access can be initiated to reuse GEO access.
